supported upon theiioor lianl' operativ" actuated means for moving the gate sections into their open positions and for maintaining the gate sections in their open positions while a vehicle is passing through the gate. The vehicle actuated means includes relatively long treadles 45, 46 positioned transversely with respect to the gate sections 2U, 2| and swingably mounted on the base frame end members I5, i6 respectively. Relatively short treadles 41, 43 are also positioned transversely with respect to the gate sections 20, 2l and are in laterally spaced relation to the long treadles and are swingably mounted on the base frame end members l5, I6 respectively. It is to be noted that the long and short treadles 45 and 4i are disposed-in longitudinal alignment with each other, as are the treadles 46 and 48. The lateral spacing of the treaclles 45 and 46 and 41 and 48 from each other is selected so that the wheels of a vehicle can engage `both sets of treadles at the same time. The long-treadle 45 has its free vend adjacent to and spaced from the gate section 2u and can'- not possibly interferewith the latter, because the gate section 26 is prevented from swinging toward the base frame end member l5. However, the treadle 41 terminates at a point spaced beyond the arcuate traverse o the gate section 28 as the latter moves from the full line position to the broken line position illustrated in Figure 1. Since the gate section 2| swings in the opposite direction, the pedal 48 extends almost up to the gate "section, while the pedal 46 is of a shorter length so that it does not interfere with the movement of the gate section 2l. Since each oi the pedals 45 to 48, inclusive, is mounted by a similar structure, it will suffice to describe only one. in detail; In Figure 6 there is shown the mounting for the pedal 45'. The adjacent end of the pedal 46 is bent to form a treansversely extending bearing 41', the free bent end of the pedal being secured upon itself by means of the l Extending along and supported on the end sill l is a link element 58 which is operatively connected to the pedals 45, 46 for connecting the pedals together. A second link element 50' is supported along the end sill I6 and is operatively connected to the adjacent pedals `41, 48 for connecting the pedals for movement in unison. Since each of the link elements 50, 56 is of a like structure, it will suice to describe only onej The link element 56, Figure 3, embodies a first arm 5l which is adapted to under-V in detail.

lie the pedal 45 and to be secured thereto by rivets, bolts or other suitable means. The element 5D further embodies a second arm 52 disposed in spaced parallel relation with respect to the arm 5l and adapted to underlie and be secured to the pedal 46. It is to be noted that the first arm 5l is of a length substantially equal to the length of the pedal 45 and the second arm 52 is of a length substantially equal to the pedal 45. The link element further embodies a pair of upwardly projecting connecting arms 53, 54, each nected together by means of the web 51, and the arm 52 is connected to the connecting arm 54 by means of the web 58. As clearly illustrated in Figure 1, the webs 56, 51 and 58 of the link element 50 are rotatably journaled on the end sill l5 by means of the spaced eyelets, generally designated by the reference numeral 59. Accordingly, upon urging the pedals 45, 46 toward the floor 11, the connectingY arms 53, 54 will be pivoted toward the gate section 26, 2|. i

Extending between the laterallyV offset end 55' of the connecting arm 53 and the adjacent post 35 of the gate section 26 is a pusher rod 66. The

operative connection or" the pusher rod 60 to the gate section 26 is made so that upon urging the connecting arm forwardly, a counterclockwise forceV will be applied to the gate section 26 to urge the latter into the broken line position illustrated in Figure 1. Operatively connected between the laterally offset end 55 of the connecting arm 54 and the adjacent vertical post 35 of the gate section 2l is another pusher rod 6l' which is connected in a -manner wherein' a counterclockwise force will be applied to theigate section 2i upon movement of the connectingarm 54 toward the gate sections. As'clearly shown in Figure 5, the operative connection between the laterally oiset end 55 of the connecting arm 53 and the adjacent pusher rod 6U is eiect'ed byl extending the laterally projectingrend through' an eyelet 62 formed on -the pusher` rod,v the laterally projecting end being heldin place by means of the transversely extending pins 83, 64.

I As clearly shownin Figure 4, the operativev con-V of which has its free end laterally offset, as de-` signated -by thereference numeral `55. The connectingarm 53 is connected to vthe farm l5l by means of the web 56, the arms 5|, 52 are conncetion between the gate post 35'andthe adjacent pusher rod 60 is effected by means of the eyelet 65 which receives the adjacent'end of thev pusher rod 60. l

As previously pointed out, the pedals 4 1, 48 are connected together byV a' link element 501 which is of the same structure as the link element 50 and embodies a pair of connecting arms l 66, 61. The connecting arm 66 is Ioperatively connected to the post 35 of the adjacent gate section 20 bymean's of the pusher rod 68 and imparts a counterlockwise force to the rotary' gate post in response to the movement of the pedals 41, 48 toward the door l1. The connection arm 61 of the link element 5I is connected Vto' the-'- rotary gate posts 35 o f thegatesection'fl by means of the pusher rod 69. From the foregoing it is readily apparent that uponV urging any oneA of the pedals 45 to 48 inclusive, vtoward the door I1, the gate sections 26, 2I-willbe swung 'into' the open position illustrated in phantom in FigureL As clearly shown in Figure 2,? the'l floor! l1 ofr the support Il isv provided with spaced longitudinally extending slots, generally designated'lby" the reference numeral 10, for the reception of the long pedals 4,5, 48, the floor' being provided with another pair of" slots, generallydesignated by the reference numeral 1I, for the reception of the short pedals 46, 41.V Accordingly, upon the vehicle urging the pedals `from the elevated `position in Figure 2 toward the floor l1, the pedalsf will be received within the slots 10, 1I to-therby present a relatively plane surface forvthe vep hicle to traverse. It isto be further noted, upon consulting Figure 2, that the entiresupport l, is mounted in the ground in amanner wherein the floor I1 of the support H appears tov be` acontinuation of the adjacent ground contours. In actual use, the gate structure l0 of the present invention can vbe installed within -a assegna inriull :lines in Figurei2 tothe depressedpositi'on illustratedin v:broken lines in Figure "-2. Afterthe'vehicle has caused 'the :gate to :swing to :the open iposition, the -continued contact with the veliicleyvheels willfmaintain thegatefin theopen position for fa :predetermined iperiod of time -dur.- ing which the car Ymay pass throughl l'the fgate. Upon :consulting the 'arrangement forL 'the 'pedals illustrated :in .Figure 1, iit iis readily apparent that one pf'thevehiclewlreels will bemaintained in contact *withfone of 'the 'pedals f'during *the period in which the vehicletraverses fthe -floor I1 of the support Il of the gate structure. Accordingly, ,the .gate will be maintained open so that the vehicle can pass therethrough. Since actuation of anyone mLthepedals-AS to 48, inelusive, will effect. the opening-of .the gate, the gate can be actuated from either side.

Although only one embodiment of the gate structure of thepresent invention has' been described,.;t is readily apparent that numerous modifications canY ybe made without departing from the inventionas set. forth :in Lthe 'appended claims.
